Fertiliser Advice for Cereals 2022

With the cost of fertiliser having trebled in many cases in the recent months this has changed the fertiliser advice that has been recommended up to now. Nitrogen prices in particular has increased dramatically since the summer 2021 and as a result is has changed the recommendations for all cereal crops based a recent review of the nitrogen response curves for each individual crop. Different cereal crops have a maximum recommended rate (Economic N optimum) of nitrogen above which it is generally not economic to apply any further nitrogen as the yield response will not cover the cost of the extra nitrogen applied, this is called the Break even Ratio (BER).  At the recent National Tillage Conference Dr. Richie Hackett explained how the nitrogen rates for wheat and barley have changed based on the changes to the BER of wheat and barley.
